Europe had human zoos in 1958

To give the simplest possible example: what gives us the right to cage a bird and disallow it from flying, which arguably is its primary purpose in life?
To be clear, I'm not following any pro animal rights, or against meat or whatever ideology. I just cannot logically make sense of holding animals in captivity with the sole purpose of having humans visit them. There are good ways to do this as well, like reservations in the open nature, where it's not a zoo, but still it's a compromise and ideally we wouldn't have to fence lions, etc. in because human settlements have expanded into their space.
Outside of preserving species, animal zoos we have now are...
...only one that makes sense is to help the population of species...
Maybe my wording was bad, but your argument is exactly what I accept as a valid reason for zoos to exist.The absurdity comes in with dog species that were bred to be small or look a certain way and are riddled with diseases or low survival chances on their own. The same kind of dog breed wouldn't survive in nature and propagate, but we believe it's acceptable to breed tiny dogs for purses or mean looking terriers that have genetic disadvantages leading to life-long ailments.
This may sound controversial, but before we protest the farming of animals whose single purpose is making furry clothes or food for humans, where those animals (like cattle, fish) wouldn't exist otherwise, we might want to fix the cruelty that's going on in some parts of the pet industry first.
To answer your question, yes, most domestication of fish falls into the same unnatural cruel captivation like caging birds, but most cat and dog domestication evolved naturally. One has to recall that domestic dogs are the result of selective breeding human friendly branches through ages. Even with those, we have dogs like German shepherd that have built-in physical conditions which are unlikely to have existed with human-intervention-free natural selection.
